Effects of Cremation on Fetal Bones.

The charring process is a weak point of anthropological analysis as it changes bone morphology and reduces information obtainable, specially in fetuses. This experiment aims at verifying the conservation of fetal bones after cremation. A total of 3138 fetuses of unknown sex and age were used, deriving from legal and therapeutic abortions from different hospitals of Milan. Cremations took place in modern crematoria. Nine cremation events were analyzed, each ranging from 57 to 915 simultaneously cremated fetuses. During the cremations, 4356 skeletal remains were recovered, 3756 of which (86.2%) were morphologically distinguishable. All types of fetal skeletal elements were found, with the exception of some cranial bones. Only 3.4% of individuals could be detected after the cremation process, because of the prevalence of abortions under 12 lunar weeks. All fire alterations were observed and the results were statistically analyzed. This pilot study confirmed the possibility of preservation of fetal skeletal elements after cremation.
